LG Network Storage Web Menu Use (for LG Network Storage administrators) - the 'syncing' state refers to the RAID configuration process, - 'migrating' indicates reconfiguring RAID - 'quarter-check' indicates setting quota for volume - 'scanning' indicates checking volume - 'sys_syncing' indicates configuring the system areas. 5 Capacity (Used/Total) The amount used and total capacity of volume are displayed. The percentage of capacity used (Used/Total) is indicated by the bar on left and full capacity (Total) is indicated by the bar on the right. Note: Total storage represents total available storage, which is defined by file system and RAID level. The ext3 file system of the LG NETWORK STORAGE occupies 1.5% of the total HDD storage, thus the actual available storage in a volume is approximately 98.5% of the total user storage. When using one HDD per volume (single disk), the total storage is equal to the actual available storage of a HDD. The total storage of a RAID- based volume differs according to RAID level (JBOD / RAID0 / RAID1 / RAID5 / RAID10). For JBOD, the total available storage is the sum of the actual available storage of each HDD. For RAID0, the total available storage is the actual available storage of the smallest HDD multiplied by the number of HDDs. For RAID1, the total available storage is the actual available storage of the smallest HDD. For RAID5, the total available storage is the actual available storage of the smallest HDD multiplied by (the number of HDDs minus 1). For RAID10, which is composed of 5 HDDS, the total available storage is twice that of the actual available storage. Note:The represented size of the HDDs differs depending on manufacturer and OS. HDD manufacturers use an exponent of 1000 while OSs such as Microsoft Windows use exponents of 1024. The total available storage on the LG NETWORK STORAGE is represented by the exponent 1024. Note: Volume storage of the LG NETWORK STORAGE is the total HDD storage without the system area and the swapping area. If for example a volume is configured with a 1TB HDD, with 1x1012 bytes of storage, user area will be as follows: 1x1012 - 10x10243 (system area) - 2x10243 (swapping area) = 987115098112 bytes. This becomes 919Gb when converted using the exponent 1024. 56

Capacity (Used/Total)
The amount used and total capacity of volume are displayed. The percentage of
capacity used (Used/Total) is indicated by the bar on left and full capacity (Total) is
indicated by the bar on the right.
Note:
Total storage represents total available
storage, which is defined by file system and
RAID level. The ext3 file system of the LG NETWORK STORAGE occupies 1.5% of the total
HDD storage, thus the actual available
storage in a volume is approximately
98.5% of
the total user storage. When using one HDD per volume (single disk), the total storage is
equal to the actual available
storage of a HDD. The total storage of a RAID- based volume
differs according to RAID level (JBOD / RAID0 / RAID1 / RAID5 / RAID10). For JBOD, the total
available
storage is the sum of the actual available storage of each HDD. For RAID0, the
total available
storage is the actual available
storage of the smallest HDD multiplied by
the number of HDDs. For RAID1, the total available
storage is the actual available
storage
of the smallest HDD. For RAID5, the total available
storage is the actual available
storage
of the smallest HDD multiplied by (the number of HDDs minus 1). For RAID10, which
is composed of 5 HDDS, the total available
storage is twice that of the actual available
storage.
Note:
The represented size of the HDDs differs depending on manufacturer and OS.
HDD manufacturers use an exponent of 1000 while OSs such as Microsoft Windows
use exponents of 1024. The total available
storage on the LG NETWORK STORAGE is
represented by the exponent 1024.
Note:
Volume storage of the LG NETWORK STORAGE is the total HDD storage without the
system area and the swapping area. If for example a volume is configured with a 1TB HDD,
with 1x10
12
bytes of storage, user area will be as follows: 1x10
12
- 10x1024
3
(system area)
- 2x1024

(swapping area) = 987115098112 bytes. This becomes 919Gb when converted
using the exponent 1024.
